config SOC_INTEL_COMMON_BLOCK_CPU
bool
default n
help
This option selects Intel Common CPU Model support code
which provides various CPU related APIs which are common
between all Intel Processor families. Common CPU code is supported
for SOCs starting from SKL,KBL,APL, and future.
config SOC_INTEL_COMMON_BLOCK_CPU_MPINIT
bool
default n
help
This option selects Intel Common CPU MP Init code. In
this common MP Init mechanism, the MP Init is occurring before
calling FSP Silicon Init. Hence, MP Init will be pulled to
BS_DEV_INIT_CHIPS Entry. And on Exit of BS_DEV_INIT, it is
ensured that all MTRRs are re-programmed based on the DRAM
resource settings.
config SOC_INTEL_COMMON_BLOCK_CPU_SMMRELOCATE
bool
depends on SOC_INTEL_COMMON_BLOCK_CPU
config SOC_INTEL_COMMON_BLOCK_CAR
bool
default n
help
This option allows you to select how cache-as-ram (CAR) is set up.
config INTEL_CAR_NEM
bool
default n
help
Traditionally, CAR is set up by using Non-Evict mode. This method
does not allow CAR and cache to co-exist, because cache fills are
blocked in NEM.
config INTEL_CAR_CQOS
bool
default n
help
Cache Quality of Service allows more fine-grained control of cache
usage. As result, it is possible to set up a portion of L2 cache for
CAR and use the remainder for actual caching.
config INTEL_CAR_NEM_ENHANCED
bool
default n
help
A current limitation of NEM (Non-Evict mode) is that code and data sizes
are derived from the requirement to not write out any modified cache line.
With NEM, if there is no physical memory behind the cached area,
the modified data will be lost and NEM results will be inconsistent.
ENHANCED NEM guarantees that modified data is always
kept in cache while clean data is replaced.
config CAR_HAS_SF_MASKS
bool
depends on INTEL_CAR_NEM_ENHANCED
help
In the case of non-inclusive cache architecture Snoop Filter MSR
IA32_L3_SF_MASK_x programming is required along with the data ways.
This is applicable for TGL and beyond.
config SF_MASK_2WAYS_PER_BIT
bool
depends on INTEL_CAR_NEM_ENHANCED
help
In the case of non-inclusive cache architecture when two ways in
the SF mask are controlled by one bit of the SF QoS register.
This is applicable for TGL alone.
config COS_MAPPED_TO_MSB
bool
depends on INTEL_CAR_NEM_ENHANCED
help
On TGL and JSL platform the class of service configuration
is mapped to MSB of MSR IA32_PQR_ASSOC.
config CAR_HAS_L3_PROTECTED_WAYS
bool
depends on INTEL_CAR_NEM_ENHANCED
help
On ADL and onwards platform has a newer requirement to protect
L3 ways in Non-Inclusive eNEM mode. Hence, MSR 0xc85 is to program
the data ways.
config USE_INTEL_FSP_MP_INIT
bool "Perform MP Initialization by FSP"
default n
depends on !USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI
help
This option allows FSP to perform multiprocessor initialization.
config USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI
bool "Perform MP Initialization by FSP using coreboot MP PPI service"
default y if MP_SERVICES_PPI
default n
help
This option allows FSP to make use of MP services PPI published by
coreboot to perform multiprocessor initialization.
config CPU_SUPPORTS_INTEL_TME
bool
default n
help
Select this if the SoC supports Intel Total Memory Encryption (TME).
config INTEL_TME
bool "Total Memory Encryption (TME)/Multi-key TME (MKTME)"
depends on CPU_SUPPORTS_INTEL_TME
default y
help
Enable Total Memory Encryption (TME)/Multi-key TME (MKTME). The spec is
available at "https://software.intel.com/sites/default/files/managed/a5
/16/Multi-Key-Total-Memory-Encryption-Spec.pdf". If CPU supports TME,
it would get enabled. If CPU supports MKTME, this same config option
enables MKTME.
config CPU_XTAL_HZ
int
help
Base clock which virtually everything runs on.
config CPU_SUPPORTS_PM_TIMER_EMULATION
bool
default n
help
Select this if the SoC's ucode supports PM ACPI timer emulation (Common
timer Copy), which is required to be able to disable the TCO PM ACPI
timer for power saving.
config SOC_INTEL_NO_BOOTGUARD_MSR
bool
help
Select this on platforms that do not support Bootguard related MSRs
0x139, MSR_BC_PBEC and 0x13A, MSR_BOOT_GUARD_SACM_INFO.
config SOC_INTEL_DISABLE_POWER_LIMITS
bool
default n
help
Select this if the Running Average Power Limits (RAPL) algorithm
for constant power management is not needed.
config SOC_INTEL_SET_MIN_CLOCK_RATIO
bool
depends on !SOC_INTEL_DISABLE_POWER_LIMITS
default n
help
If the power budget of the mainboard is limited, it can be useful to
limit the CPU power dissipation at the cost of performance by setting
the lowest possible CPU clock. Enable this option if you need smallest
possible CPU clock. This setting can be overruled by the OS if it has an
p-state driver which can adjust the clock to its need.
config HAVE_HYPERTHREADING
def_bool n
config FSP_HYPERTHREADING
bool "Enable Hyper-Threading"
depends on HAVE_HYPERTHREADING
default y
